Plant biology:  Good neighbours

Laura Serna1

Plants depend on structures called stomata to regulate gas exchange with the air, and their positioning is crucial. A key factor controlling stomatal development and arrangement has now been found.

We all need good neighbours, but plant guard cells need them more than most. Destined to remain where they are produced, these cells cannot function efficiently without help from adjacent cells.
